Auto Answer Or AgentLogin Stay On The Line?

I am considering what are the best option for Agent to Login and and wait for the calls from the Queue.

Option 1: AgentLogin (staying on the line with music on hold and bridging the call when a customer enters the queue)

Option 2: After AgentLogin then enable Auto-Answer feature on the SIP
Phones.

I am considering going for Option 1 because it will work on any sip phones but it might be impossible to use AgentLogin if calls are distributed to many queues on multiple servers and leastrecent would not work?
